12-Point flange screws, also known as Ferry Bolts are high-strength fasteners where the flange diameter and head thickness of the 12-Point Flange Screw are equivalent to the head dimensions of a socket head cap screw, thus permitting the 12-Point Flange Screw to be a replacement for any application that calls for a socket head cap screw. The 12-point head design means that this screw can be tightened with a 12-point socket wrench which allows higher torques to be applied as compared to a standard internal hex drive socket head cap screw. The head or wrench size is the same as the body size.
